Cleaning
Do not clean with solvents or abrasive cleaners. Some household or commercial
cleaners can react with painted surfaces or panel markings.
Do not apply excessive amounts of detergent cleaner. It may seep into electrical circuits
within the base and cause equipment failure.
Do not use too much oil. It attracts abrasive particles that may accelerate wear.
Use low pressure air to blow dust. Do not direct the air stream directly at sensitive
components.
It is recommended that the machine be cleaned weekly, or more often if it is operating
in a dusty or dirty environment.
To clean the load frame, wipe exterior surfaces of the load frame with a moist cloth.
If your machine has a maximum capacity of 50 kN or greater (all floor models and some
table models) and if the central mounting area on the base beam is exposed (no base
adapter is in place) then you must regularly lubricate the mounting area with oil to
prevent corrosion. If you regularly use a base adapter, then you do not need to lubricate
this area (refer to “Lubrication” on page 113).
Lubrication
The following areas of the machine will require periodic lubrication:
• Ballscrews - The ballscrews are lubricated via a ballnut that is located on the
crosshead where the ballscrew intersects the crosshead. As the crosshead moves
up and down, the ballnut disperses a thin layer of lubricant over each ballscrew as
the ballscrew passes through the ballnut. Periodically, the ballnut must be filled with
lubricant to ensure that the ballscrews remain well lubricated. The ballnut must be
maintained and filled in accordance with Table 9 on page 114.
Inspect the ballscrew and lubricate more frequently if any of the following conditions
exist:
• There is high-load or high-speed testing.
• There is long-term, continuous movement of the crosshead.
• The system operates in a dirty environment.
• There are high-load cycling tests.
